After graduating with a bachelor's degree in vocal performance from Loyola University New Orleans, Peiser continued her vocal studies throughout graduate school. She has performed early music with several ensembles in the northeast (including Schola Cantorum in Boston) as well as contemporary repertoire at the College Music Society, Bowdoin International Music Festival, Women Composers Festival of Hartford, and Hartford Opera Theater. Roles in her repertoire include Mimí in La Bohème, Pamina in Die Zauberflöte, and the eponymous character of Charpentier's Louise. She has served as featured soloist for Haydn's Lord Nelson Mass, Bach's Magnificat, Händel's Messiah, and Mozart's Requiem. Always looking to expand her repertoire, Peiser has recently joined the Andrews Sisters-inspired vintage jazz vocal trio, the San Diego Muses.
